Problem when reinstalling Windows, please help

[nowa]

Hi all,

I posted this as a question in on of the reviews as well… Sorry, it probably doesn’t belong there… but the problem I’ve got is that I have a 64GB HG9M, BIOS and partitions are all stock but I have upgraded the Android ROM to Tecknights (great ROM) and I have upgraded to Windows10.

I then decided to give the tablet to a friend and did a “reset PC” in Windows10… Well big mistake… Stuck at 66% for hours, tried to reboot and repair, ended up with a black screen which did nothing in windows (Android is still fine)

So, my only option (it seemed) was to reinstall windows, but I get stuck when choosing “custom installation of windows” as I then get to choose which partition I should use, since I still have all my Android partition(s) (and I want to keep Android) I choose the old windows partition (38GB) worth mentioning is that I had to delete it first to get about 38GB unallocated space and then I had to choose this unallocated space to install on, but doing this brings up a message on the installer saying “the partitions on the disc selected for installation are not in the recommended order…..” and you have an option to cancel or proceed anyway, ignoring this and selecting OK gets you to the next point when the installer should start to copy files, but this never starts (0%) instead the installer throws a prompt saying “windows detected that the EFI system partition was formatted in NTFS. Format the EFI system partition in FAT32 and restart the installation”

 

In total I have 18 partitions (all as factory) the first one is a ESP partition (64MB) which is a “system” partition from the original (factory) installation, it looks important so I haven’t touched it. Then partition 17 also looks important, “MSR reserved” 128MB, again, I haven’t touched it, and partition 16 is “system” 100MB, all of them from factory default, as I have not touched them, the only partition I deleted was partition 18 where the old windows was, this is now the unallocated space which I can’t install to… Any ideas what I should do? Which partition should I get rid of to get windows to install and I would as mentioned like to keep my Android part?

So, looks like I’ve managed to answer my own question, I had to delete the last (18th) partition, I also had to delete the 17th system partition, also the 16th MSR partition.

After that the windows installer finally allowed me to install a new fresh version of win10 onto the unallocated space.
